My bear is now 51 (almost 52, actually). I started for a tweaked dual-spec and my stats are STR 140 / DEX 119 right now, and I wear STR weapons. I used part of money gained during levelling for buying some equipment and did all AO3 quests, so now I have Mystery set, both Cyber Rift Sets, and both Gurgox and Sunblessed Rift sets.

Today question is: It worth to use +350K for a Guardian set now? Or I achieve better results starting to use yellow/green BS items once I reach 53?

(I did the same with my bird and my mage before - lev 51 BS yellows/greens was poor in comparison with L50 full sets).
